In the laboratory, surfaces must be disinfected for blood spills. What is the most common disinfectant used?

A regional laboratory that performs high volume, highly complex or infrequently ordered testing is a:

Clostridium difficile is a gram-positive, spore-forming bacilli. The remaining organisms will all stain gram-negative on direct smear or smears made from culture.
Which of the following organisms are gram-positive?

PCT usually rises within 3-6 hours of infection. CRP also increases rapidly following infection, but is not as specific for infection as PCT. A rise in CRP could also occur with SIRS. Lactic acid is usually used to detect and monitor impaired circulation and tissue oxygenation in critically ill patients.
Chemistry
Of the three laboratory tests that are listed, which has proven to be most effective for early differentiation of systemic inflammatory response syndrome (SIRS) from sepsis due to its increase following infection and higher specificity?

In DNA complementary base pairing, guanine and cytosine pair and adenine and thymine base pair.
Remembering the phrase "G-CAT" helps one recollect correct pairing.
Which nitrogen base would bind with a guanine nucleotide in forming double-stranded DNA?
